Water Temp Gauges, what are you using?
You guys using aftermarket water temp gauges, what are you using (brand)? Where are you getting your signal from without replacing/interrupting the factory water temp signal to your MS?
I've got an autometer phantom water temp gauge that was given to me, its electric short sweep style and I need a temp sender for it but I dont want to interrupt my water temp signal to my MS for obvious reasons. Help? |
I am using a autometer as well i mounted it in the spacer for the coolant reroute
|
Omori because I'm better than you.
|
Stock, linearized.

Joe, I just did a quick search under you name. Searching for linear, water, coolant, sensor, etc. and could not find a thread showing your linearaztion of the gauge. Not that I could do it anyway. Electrical moron here. Anyway one of these days you and Abe need to come up to the Bear, for some mountain biking. There will be tons of good beer, fish tacos, and you can do your magic on my car, making it super bitchin. Just let me know, I'll start grillin.

On all Miatas 1989-2005, the dash gauge and the ECU are fed by two different sensors. In the '99 and later cars, these two sensors are in the same housing, but are still electrically isolated. |
VDO gauge. Extra sensor close to the rad inlet.
|
pix of the other sender anybody?
|
|
I'm assuming your speaking of the brass adapter you have in the rad hose?

VDO Vision gauge, stock sender location re-tapped to accept the 1/8-27 npt VDO sender.

Yep, it only feeds the temp gauge on the dash.

I recently installed this SPA Design dual oil & water temp gauge. The water sender is in the spare port of the M-tuned reroute housing on the back of the head. If you don't have a pre-tapped reroute housing, you can use one of the radiator hose adapters, or a similar style of adapter sized to fit the heater core hose. Pegasus sells both sizes.
Attachment 197007 The gauge seems to read about 10*F low once the car is warmed up, but it has a service menu that you access with the push-button (hidden away) that can supposedly be used to manually calibrate it. I haven't gotten around to messing with it yet. |

The sensor itself is fairly linear, but you can't just feed it into an aftermarket gauge- the calibration is wrong.

+1. I ran it side by side with an aftermarket gauge for comparison (co-located sensors) and it works well.

Ahhh ok, are they both 1 wire? I know there is a 1 wire on my 95 right near my heater hoses and I'm assuming this one is the ECU sender you speak of.
|
I am in for linearization? of the factory gauge :)
|
Mines connected in the back of the heads heater hose and the other hose that goes inside the firewall. I made a T from home depot and stuck the sensor in there.
|
first 1/2 of the gauge is warm up and operational temp. second 1/2 is where the needle goes after you start over heating |
